edges when i apply pan&crop
Hi everyone,
I have a clip which I want to apply a flash and then slightly twist the b&w image…. so it looks like someone has taken a photo (I am using 2 frames of a white background text media slide as the flash). My problem is after the flash, I have taken a still of the last frame, applied B&W and it looks great up to the point I try to add a slight twist with pan&crop – the edges are really jagged and the whole image has waves across it as it moves…
Any help gratefully received.

I suppose the waves are only in the preview window? What happens when you increase the resolution of the preview window? Or when you (pre)render this effect? Probably the edges will look fine then.

i did pre render it and it look pretty much the same, i also checked the properties of the still which are at a high res than the footage (not sure how to change that) and it was progessive scan (which i changed to upper first to match the footage). ?

What kind of file-type is your footage? And did you make the framegrabs as .jpg or as .bmp?

Hi Theo,
Footage is HDV 1080i 50 and the grab was jpeg? – the preview window was set to hights res for the grab?

Instead of taking a snapshot, try this. Zoom into the very last frame, the one you want to freeze, and split it. Change the velocity of this single frame to zero to freeze it. You can now drag this out for as long as you want it. You can also move this clip to a new track and make it 3D to give any Z axis movement. For the flash, I really like the ‘Dissolve – Fade Though White’ transition and make it about 6-8 frames for the photo-flash effect. Hope this helps.

I should note you don’t have to move your freeze frame to another track to make it 3D. You can make the current track you are using 3D.

Thank you James, great advice. Martin.

When resizing or modifying still images in Vegas in 99% of cases it’s best to make sure that you have ‘reduce interlace flicker’ selected on the modified, distorted or resized images, works well for video also. Right click on the images and select ‘Switches’ and then select the ‘Reduce interlace flicker’ option. Finally set you Project Properties to ‘Best’ under the ‘Full-resolution rendering quality’ drop down selection menu. In the bulk of cases those jaggies and wave type line lines you are seeing will not be there when your video is rendered. Selecting ‘Best’ will increase the render times a little but at least you get good results, well worth the trade off.

Hi James.

How does one split a frame?
And why split it? What advantage does that give?
Thank you,
Norman
